Anders Carlsson bae46277fe Always emit vcall offset for the primary base, not only if it's virtual. Remove a debug printf, and add the test case that now passes.

Anders Carlsson 510d22d097 Simplify the vcall offset calculation and make it give the correct answers :) My test case now has the right values but in the wrong order.

Anders Carlsson 30f5301e54 More work on vcall offsets. We now emit the right number of vcall offsets in my local test case, but not the right values.

Chris Lattner a828850b4d X86InstrInfoSSE.td declares PINSRW as having type v8i16, 
don't alis it in the MMX .td file with a different width,
split into two X86ISD opcodes.  This fixes an x86 testcase.

Chris Lattner fbbe2617dc the cell backend is making all sorts of unsafe and incorrect assumptions 
about ownership and update policies.  It isn't clear why it is doing all
this lowering at isel time instead of in legalize.  This fixes fcmp64.ll

John McCall f8ff7b9fd1 Perform two more constructor/destructor code-size optimizations: 
1) emit base destructors as aliases to their unique base class destructors
under some careful conditions.  This is enabled for the same targets that can
support complete-to-base aliases, i.e. not darwin.

2) Emit non-variadic complete constructors for classes with no virtual bases
as calls to the base constructor.  This is enabled on all targets and in
theory can trigger in situations that the alias optimization can't (mostly
involving virtual bases, mostly not yet supported).

These are bundled together because I didn't think it worthwhile to split them,
not because they really need to be.

Douglas Gregor 46841e1bd9 Implement crazy destructor name lookup semantics differently in 
C++98/03 and C++0x, since the '0x semantics break valid C++98/03
code. This new mess is tracked by core issue 399, which is still
unresolved.

Fixes PR6358 and PR6359.

Chris Lattner 60680ad316 add a new Push2 opcode for targets (like cellspu) which have 
ridiculously ginormous patterns and need more than one byte
of displacement for encodings.  This fixes CellSPU/fdiv.ll.
SPU is still doing something else ridiculous though.

Evan Cheng 3688b8fa68 Instcombine constant folding can normalize gep with negative index to index with large offset. When instcombine objsize checking transformation sees these geps where the offset seemingly point out of bound, it should just return "i don't know" rather than asserting.

Chris Lattner d0b16bd219 Change ComplexPattern handling to push the node being matched as 
well as the operands produced when the pattern is matched.  This
allows CheckSame to work correctly when matching replicated 
names involving ComplexPatterns.  This fixes a bunch of MSP430 
failures, we're down to 13 failures, two of which are
due to a sched bug.

Douglas Gregor d770f73fac Rework the CIndex API for displaying diagnostics. Instead of printing 
the diagnostics to a FILE*, return a CXString containing the formatted
diagnostic.

Jim Grosbach 45fceea0e4 Updated version of r96634 (which was reverted due to failing 176.gcc and 
126.gcc nightly tests. These failures uncovered latent bugs that machine DCE
could remove one half of a stack adjust down/up pair, causing PEI to assert.
This update fixes that, and the tests now pass.

Jim Grosbach 15f6ed348f The predicate index isn't fixed, so scan for it to make sure we get the proper 
value.

Thumb2 uses the tADJCALLSTACK* instructions, and doesn't need t2 versions, so
remove the FIXME entry.

Dan Gohman 6c5ac6de5c Canonicalize ConstantInts to the right operand of commutative 
operators.

The test difference is just due to the multiplication operands
being commuted (and thus requiring a more elaborate match). In
optimized code, that expression would be folded.

Chris Lattner 85ef93f130 expand my hack to work with nodes that have flags but no chains and the 
isel doesn't know the correct # results.  This fixes 8 codegen tests,
down to 22 failures.

 2010-02-22 22:37:11 +00:00
Chris Lattner bb2afb79c0 add a new CheckMultiOpcode opcode for checking that a node 
has one of the list of acceptable opcodes for a complex 
pattern.  This fixes 4 regtest failures.

Chris Lattner a5a298517e When matching patterns that have a complex pattern as their root, make 
sure to only run the complex pattern on nodes where the target opts in.
This patch only handles targets with one opcode specified so far, but
fixes 16 failures, only 34 left.
